Network Penetration Testing. Secure your infrastructure.

Your network is the backbone of your business. Misconfigurations, unpatched systems, and weak credentials create attack paths attackers exploit daily. Our experts test internal and external networks to find vulnerabilities before they become breaches.

Network Security Reality

Why network security matters

Network infrastructure continues to be a high-value target for sophisticated attackers. Outdated systems, limited segmentation, and complex environments increase exposure - putting critical assets, business operations, and regulatory compliance at risk.

The Challenge

Network security challenges

Today’s enterprise networks are complex, hybrid, and constantly changing. This complexity increases exposure and makes consistent security controls harder to enforce across the environment.

Legacy systems

Old servers, unpatched systems, and EOL software create easy entry points. Legacy isn't going away, but it needs protection.

Windows 2012 EOL

Active Directory complexity

Years of accumulated permissions, nested groups, and legacy GPOs. AD is often the weakest link, and the keys to the kingdom.

AD Kerberos

Flat network architecture

Lack of segmentation means one compromised host leads to full network access. Once in, attackers move freely.

VLANs Segmentation

Remote access sprawl

VPNs, RDP, SSH, and cloud access points. Each remote access path is a potential entry point for attackers.

VPN RDP SSH

Credential hygiene

Weak passwords, shared service accounts, and cached credentials. Attackers don't hack in, they log in.

Passwords MFA

Limited visibility

What you can't see, you can't protect. Shadow IT, rogue devices, and undocumented systems create blind spots.

Asset Inventory

Perimeter erosion

Cloud, SaaS, and remote work have dissolved the traditional perimeter. Trust no network, internal or external.

Zero Trust

Patch management

Keeping up with patches across hundreds of systems is hard. Attackers only need one unpatched vulnerability.

CVEs Updates

Detection gaps

Firewalls and IDS aren't enough. Modern attackers live off the land using legitimate tools to avoid detection.

SIEM EDR
Your Advantage

Benefits of professional network testing

Expert-led testing that emulates real-world attack techniques to identify exploitable paths to critical systems before they can be leveraged by attackers.

Compliance evidence

Reports mapped to PCI DSS, SOC 2, ISO 27001, and NIS2. Satisfy audit requirements with professional testing.

For IT/Security Teams

Requirement mapping, technical evidence, remediation priorities

For Leadership

Audit-ready reports, compliance evidence, reduced regulatory risk

Credential testing

Password spraying, hash cracking, and credential reuse testing. Find weak authentication before attackers do.

For IT/Security Teams

Password policy validation, credential hygiene assessment, MFA testing

For Leadership

Prevent account takeover, protect against credential-based attacks

Improve security posture

Clear remediation priorities based on real-world exploitability, not just CVSS scores.

Our Methodology

How we test your network

Our methodology combines industry frameworks (PTES, NIST) with real-world attacker techniques used in advanced persistent threats.

01
Day 1

Scoping & rules of engagement

Define scope (IP ranges, domains, systems), establish rules of engagement, and coordinate testing windows with your team.

Kickoff call Scope definition IP ranges Testing windows Emergency contacts Out-of-scope systems

Common Questions

Frequently asked questions

Answers to common questions about network penetration testing.

External testing simulates an internet-based attacker targeting your public-facing services: VPNs, web servers, mail gateways, and exposed ports. Internal testing simulates a threat actor who already has a foothold inside your network: a compromised employee, malicious insider, or post-breach scenario. Most organizations need both for comprehensive coverage.

We use controlled testing techniques designed to minimize disruption. We coordinate testing windows with your team, avoid denial-of-service attacks unless specifically scoped, and have emergency contacts established. In 11+ years of testing, we've never caused an unplanned outage.

External testing typically takes 3-5 days. Internal testing takes 5-10 days depending on network size. Active Directory assessments add 3-5 days. Comprehensive internal + external + AD testing for a mid-size organization usually takes 2-3 weeks.

Yes, AD security is a core capability. We test for Kerberoasting, AS-REP roasting, GPO abuse, delegation attacks, ACL misconfigurations, certificate services (ADCS) vulnerabilities, and privilege escalation paths. AD is often the fastest path to domain admin.

For internal testing, we need network access equivalent to a standard employee: a workstation or laptop connected to your network, either on-site or via VPN. We can test from your office or remotely via secure tunnel. Credentials are not required for black-box testing, but can accelerate gray-box scenarios.

Yes, segmentation validation is included. We attempt to move between network zones, test firewall rules, and validate that critical assets are actually isolated. This is crucial for PCI DSS scope reduction and protecting high-value targets.

Both. We use industry-standard tools for reconnaissance and vulnerability scanning, but the real value is in manual testing: chaining vulnerabilities, exploiting trust relationships, and finding attack paths that automated tools miss. Our testers have OSCP, OSCE, and CREST certifications.

Network penetration testing satisfies requirements in PCI DSS (11.3), SOC 2 (Common Criteria), ISO 27001 (A.14.2.8), NIS2 (security testing), HIPAA (technical safeguards), and most cyber insurance policies. Our reports include compliance mapping.

Discovered credentials (passwords, hashes, certificates) are documented as vulnerabilities and handled securely. We don't retain credentials after the engagement. If we crack password hashes, we report weak password patterns without including the actual passwords in the final report.

Yes, we typically test during business hours to simulate realistic attack scenarios. For internal testing, daytime testing also catches configuration issues that only occur during normal operations. We can adjust testing windows if you prefer off-hours testing.
